Question 1053025: Convert the complex number -5i from rectangular form, to polar form. I don't know how to convert it. Answer by KMST(5328) (Show Source):
You can put this solution on YOUR website! For 0-5i, plot point P(0,-5),
with the real part as the x-coordinate,
and the imaginary part as the y-coordinate. is the distance to the origin, O(0,0). (or in radians) is the angle OP forms with the positive x-axis,
measured counterclockwise from the positive x-axis.
